摘要
亥姆霍兹于 15 0年前发明的研究语言和听觉的唯一利器———亥姆霍兹共鸣器 ,是放大、扩声。
An empty spherical container with a short tube inserted makes a resonator which Helmholtz invented as the only instrument to start his speech and hearing investigation,about 150 years ago. Helmholtz resonators amplify, reenforce and absorb sound without the help of electronics.
